Description

A kind of BIM and the construction design method of the two-way insertion of software for calculation
Technical field
The present invention relates to structure-design technique field, particularly a kind of BIM and the structure design of the two-way insertion of software for calculation Method.
Background technology
BIM is ((Building Information Modeling) as a kind of emerging Three-dimensional Design Technique, nearest More than ten years, be gradually widely used in the design of engineering construction, construction, O&M stage.But in the design of engineering Stage, structure discipline designs still very delayed using BIM, and it is the specialties such as building, electromechanics typically passively to create BIM models Use, hardly actively use BIM technology to carry out structure design.To find out its cause, carrying out structure design, effect using BIM technology Rate is significantly less than traditional two-dimensional design mode unexpectedly.
Therefore, having been carried out the research of about 10 years both at home and abroad, multiple plug-in units are developed, BIM is realized and Structure Calculation is soft The connection of part.It is summed up, there are following three kinds of modes:1) structural computational model is read in BIM platforms;2) by the three-dimensional moulds of BIM Type and fractional load write-in software for calculation;3) model and the load bi-directional between BIM and software for calculation.The reality of 1st kind of mode Matter is centered on software for calculation, first to carry out Structure Calculation and then create BIM models and drawing, this method flows with common design Cheng Bufu, it is impossible to the extensive use in structure design;When reading in the computation model changed from BIM platforms, mould must be carried out Type contrast, one by one confirm modification part be by computation model be defined also be to maintain it is constant, operate it is quite cumbersome;Import every time new Computation model, hole, embedded part, buttress, mark, size marking in BIM drawings to changing component association etc. are both needed to corresponding benefit Fill and change, workload is big, easily malfunctions.2nd kind of mode, when BIM models have change, re-writes after software for calculation, Need to be checked and changed accordingly in software for calculation, and examine, change and supplement at the modification load on periphery and Related setting, it is quite cumbersome.Therefore engineer is in structure design, to ensure correctness, it is to avoid cumbersome verification, modification and benefit Work is filled, usually only the computation model, follow-up modification adjustment difference is generated using BIM models when creating computation model first Completed manually in BIM models and software for calculation.3rd kind of mode, engineer needs the moment to keep current newest mould firmly in mind Type is on earth at which side in order to avoid pass wrong direction, and BIM Model Transfers are not to being avoided that week for searching and examining at modification after software for calculation Side load and related setting it is cumbersome, import that computation model can not solve model contrast and association diagram element is lost asks in BIM Topic.
As can be seen that current connected mode, is only merely to realize BIM models and turn of computation model partial data Change, do not make full use of the technical characterstic of BIM platforms, cause structure BIM design efficiencies low, be only capable of meeting the construction of simple structure G- Design requirement, it is impossible to be widely popularized in the BIM designs of structure, cause current structure specialty to be reluctant actively to use BIM technology The situation being designed.
